Ta aZZ whom it may concern.'

Be it known that I, WILLIAM MILLER, a citizen of the United States,and a residentof Woonsocket, in thecounty of Providence and State of Rhode Island, have invented `certain new and useful Improvements in Shaft-0ouplings; and I do declare the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which v it appertains' to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. v,

Figure l of the drawings is a side View. Fig. 2 is a vertical section taken on line fr x, Fig. l. Fig. 3 is a vertical section taken on line g/ y, Fig. l. c

This invention relates to couplings for shafts; and it consists in the Constr-notion Vand novel combination of parts as hereinafter described, and pointed out in the claim.

In the accompanying drawings, the let-ters A A designate the longitudinallydivided halves or sections of the coupling-clamp, and B B -the coupling-sleeves, which are forced toward each other and upon the hub portions C of the coupling-sections by means ofthe bolts and nutsD.

The sectional couplings A A have the halfhubs O and the central flanges, E, extending outward therefrom, said flanges terminating in the rim portions F, which are of sufticient breadth to cover in from front or center view the bolt-heads and nuts employed in the coupling. The half-hubs Gare turned in taper form and the flanges are provided with apertures G, through .which the coupling-bolts pass. The

sections are usually provided with the proj ecting edge-lugs H, which are adapted to register with and enter corresponding recesses in the opposite sections respectively, to prevent these sections from movinglengthwise away` from each other on the shafting. The shafting is grooved to receive the key L, which also tits a grooved seat in the coupling, preventing the latter from turning on t-he shafting.

The flanged sleeves B B have also the taper form, and are designed to lit over the hub portions of the couplingsections at each end. The anges N of the sleeves are at their inner ends, and approach the flange of the coupling sections when in position. sleeves conforms to that of the hub-sections, so that when drawn together by means of nuts and the bolts which pass through apertures therein, they will be bound on the hubs, and will cause the latter to forcibly clamp the shafting, a slight clearance being left between theI sections of the eouplingto permit theml to approach eachother slightly under the action of the sleeves.

By means of set -screws Z, and through threaded seats in the Bauges of the sleeves and engaging the center flanges of the coupling-sections, the sleeves can be forced backward and removed when advisable.

Having described thisinvention,wl1atl claim and desire to secure by Letters Patent, is-

The combination ofthe longitudinallydi vided coupling-clamps having taper hub por tions, registering lugs and recesses, and perforated tlanges, tapering coupling-sleeves having perforated flanges at their inner ends, and coupling bolts and nuts, substantially as speciiied.

In testimony whereof Iatx my signature in `presence of tw'o witnesses.
